ELECTION: Obama closer to 270-vote threshold

COLUMBUS, Ohio - President Barack Obama enters the final hours of the 2012 campaign with an edge in the hunt for the 270 electoral votes needed to win and more ways to reach that magic number. Yet the race is remarkably close in at least six states that could go either way, giving Republican Mitt Romney hope that he can pull off a come-from-behind victory.

If the election were held now, an Associated Press analysis found that Obama would be all but assured of 249 votes, by carrying 20 states that are solidly Democratic or leaning his way - Iowa, Nevada and Pennsylvania among them - and the District of Columbia. Romney would lay claim to 206, from probable victories in 24 states that are strong Republican turf or tilt toward the GOP, including North Carolina.

Up for grabs are 83 electoral votes spread across Colorado, Florida, Ohio, New Hampshire, Virginia and Wisconsin. Of those, Republicans and Democrats alike say Obama seems in a bit better shape than Romney in Ohio and Wisconsin, while Romney appears to be performing slightly better than Obama or has pulled even in Florida and Virginia.

The AP's analysis is not meant to be predictive, but instead to provide a snapshot of a race that has been extraordinarily close from the outset. The analysis is based on interviews with more than a dozen Republican and Democratic strategists in Washington and in the most contested states; public polls; internal campaign surveys; early vote figures; spending on television advertising; candidate travel; and get-out-the-vote organizations.

Both Republicans and Democrats say Tuesday's election has tightened across the board the homestretch. Many factors are adding to the uncertainty, including early vote tallies, Election Day turnout and the impact of Superstorm Sandy in the East. There's no telling the impact of Libertarian Party candidate Gary Johnson, who's on the ballot in 48 states, including all the battlegrounds, or Virgil Goode, an ex-congressman from Virginia who's running on the Constitution Party ticket.
